附加信息

Historical Context: This 20 Réis copper coin, originally issued during King Pedro V's reign (1853-1861), signifies a practical solution in Portuguese colonial monetary history. The distinctive "Small Crown" countermark, applied in 1854, officially designated the coin for circulation in São Tomé and Príncipe. This measure addressed a chronic shortage of small change within the West African colony, a common challenge for distant colonial administrations lacking dedicated local mints.

Artistry: The original 20 Réis coin, produced by the Lisbon Mint, reflects the neoclassical stylistic school prevalent in mid-19th century European coinage. Its design featured a youthful, laureate bust of King Pedro V on the obverse and the Portuguese royal coat of arms on the reverse. The "Small Crown" countermark, however, is a purely utilitarian element. It is a simple, stylized crown impressed onto the coin's surface, serving an administrative function rather than an artistic one, often partially obscuring original design elements.

Technical/Grading: For this countermarked 20 Réis, key high-points for wear on the original coin include the highest strands of Pedro V's hair and the crown elements of the royal shield. The strike quality of the original copper planchet can be variable. Crucially, the countermark's impression is a primary grading factor; a sharp, deep, and well-centered crown is highly desirable. Collectors should also note any metal displacement or flattening on the reverse caused by the countermarking process, and copper's typical susceptibility to environmental corrosion.
